Answer:
Step-by-step explanation:
Although you can start with 4x^2-2x-4=0, it's just slightly easier to reduce the coefficients. 4x^2-2x-4=0 becomes 2x^2 - x - 2 = 0.
The discriminant (part of the quadratic formula) is b^2 - 4ac. Using b = -1. a = 1 and c = -2, we get (-1)^2 - 4(2)(-2), or 17.
-b ± √(b^2 - 4ac)
Then the quadratic formula x = ---------------------------
2a
-(-1) ± √17 1 ± √17
takes on the values x = ----------------- = ---------------
4 4
The Jasmine result is the good one because 1 mégas meter=1 000 000
Given:
weight of mixture : 1792 ounces
output of mixture : 560 bars of soap
to get the weight per unit, we simply divide by total weight by the total number of output.
1792 oz / 560 bars = 3.2 ounces per bar.
